About Donutleaks

Donutleaks is a ransomware group that emerged in August 2022, operating with primarily financial motivations and demonstrating a pattern of targeting critical infrastructure and business sectors across multiple countries. The group's origin and specific affiliations remain largely undocumented in publicly available threat intelligence reports, with limited information available from major security firms or law enforcement agencies regarding their operational structure or potential ransomware-as-a-service model. Based on the limited public documentation available, the group has demonstrated a preference for attacking healthcare, technology, manufacturing, business services, and telecommunications sectors, with their attack methodology and specific technical capabilities not extensively detailed in current threat intelligence reporting. Donutleaks has been associated with approximately 42 documented victims primarily concentrated in the United States, Italy, Iran, and Spain, though specific high-profile campaigns or ransom demands have not been widely reported by major cybersecurity organizations or law enforcement agencies. The current operational status of Donutleaks remains unclear due to limited public threat intelligence coverage of this particular threat actor. The group has been linked to 42 public disclosures across our corpus. First observed on a leak site on August 24, 2022; most recent post July 24, 2024. The operation is currently inactive.
